--- Comment #1 from Thomas Lübking <thomas.luebk...@gmail.com> --- Qt 5.6.0? https://bugreports.qt.io/browse/QTBUG-42985 > By setting the QMainWindow widget to minimized and then putting it back to > normal, the > windows show up in kwin_x11 tabbox and the task manager again: When this happens again, please run "xwininfo -tree -root" and check whether the X11 windows are still present (and mapped, you can pass their id to "xwininfo -id 0x123456" to inspect their mapping state) The bug is probably rather the missing resize in the tabbox than the same "confusion" in kwin_x11 and plasmashell. I thus predict the windows are either gone or unmapped (notably since only Qt5 clients are affected) -- You are receiving this mail because: You are watching all bug changes.
